Granted: 1984-03-21
Abstract: The invention relates to a method permitting ferromagnetic powders to be readily tested for their qualification for use in heavy medium suspensions for the float-sink dressing of minerals. To this end, the invention provides (a) for ferromagnetic powder particles with a size within the range 63 to 100 mu  to be admixed with a quantity of a glycerol/water mixture necessary to obtain a heavy medium suspension having a specific density within the range 1.45 to 1.55 g/cm3; (b) for the heavy medium suspension to be demagnetized in a cyclicly decreasing alternating field at maximum field strengths within the range 1200 to 1600 amperes/cm and for its relative sedimentation velocity to be determined by means of a sedimentometer; (c) for the demagnetized heavy medium suspension to be magnetized in a magnetic steady field at field strengths within the range 700 to 900 amperes/cm and for its relative sedimentation velocity to be determined by means of a sedimentometer; and for (d) the magnetized heavy medium suspension to be demagnetized in a cyclicly decreasing alternating field at maximum field strengths within the range 1200 to 1600 amperes/cm and for its relative sedimentation velocity to be determined by means of a sedimentometer. Ferromagnetic powder is fully serviceable for use in heavy medium suspensions in the event of the relative sedimentation velocity determined in step (b) being smaller than 0.25 cm/second, that determined in step (c) being greater than 2.5 cm per second and that determined in step (d) being smaller than 0.4 cm/second.

Abstract: The medullary canal plug is formed by a deformable and expandable outer body having a jacket formed of a number of segments and a conical expansion body which is pulled into the outer body in order to expand the outer body. Spreading of the outer body causes barb-like anchoring elements to hook into the inner wall of a bone. The two bodies are permanently secured together via serrations on the inside of the outer body and the outside of the expansion body.

Abstract: In a trunk circuit for digital signals, a digital subtracting circuit (3a) and an adaptive transversal filter (7) are inserted in a shunt branch between the transmitting path (6) and the receiving path (19). On the trunk circuit (6,19), digital signals are transmitted in the original frequency band from 0.3 to 3.4 kHz. A direct voltage or a digital sweep or noise signal in the original frequency bands 0 to 0.3 and 3.4 to 4 kHz, which are generated in the digital additional-signal generator (15a), are superimposed on such a received signal via a digital adding circuit (11a). This prevents the coefficients from escaping from a predetermined band. When analog/digital and digital/analog converters are inserted for digital operation of the adaptive transversal filter (7), connection to analog trunk circuits is also possible. These echo compensators are used, in particular, in international gateway exchanges. <IMAGE>

Granted: 1992-03-04
Abstract: Filtering apparatus for removing combustible particles from a gas, e.g. carbon and hydrocarbon particles from the exhaust gases of a diesel engine, comprises at least one filter element 23 which is made of fibrous material and is electrically conductive. To remove trapped particles from the filter element 23 and thereby regenerate the filter element, electrical power is supplied to the filter element to heat it to the point at which the carbon and hydrocarbon particles combust. One or a plurality of such filter elements 23 may be provided in a housing 20 in the exhaust gas system of a diesel engine with the filter elements exposed in parallel to exhaust gases. For regeneration, all filter elements may be simultaneously regenerated while exhaust gases are either exhausted direct to the air or through a similar filtering apparatus. Alternatively the filter elements may be regenerated sequentially so that at least some of the filter elements are always effective as filters. During regeneration exhaust gases are substantially excluded from a filter element undergoing regeneration and this may be effected by preventing flow of the exhaust gases to the filter element while it is being regenerated or by increasing the pressure downstream of the filter element to prevent exhaust gases flowing through the filter element. Each filter element 23 is preferably annular and arranged so that exhaust gases flow through the wall in a radially inward direction.

The seal holder 28 is secured to the frame 18 and has a pair of spaced flanges 41,42 extending in a direction generally away from the respective lens 17. Space between the flanges of the seal holder provides a groove 58 extending around the eye piece and the seal holder is resiliently deformable but relatively stiff. The seal gasket 30 is fitted within the groove between the flanges 41,42 and has an outer face 60 standing clear of the flanges to contact the wearer's face. The seal gasket 30 is resiliently deformable and softer than the seal holder 28 to provide a secure but comfortable seal with the wearer's face. Selection of the relative resiliences of the seal holder 28 and seal gasket 30 permits accommodation to a wide variety of faces and extends use of the goggles. A face mask with a single lens provided with a seal assembly as above is an alternative.
